Installation
Dual Filtration (GEH 1/2
to 5 ton)
Note: The dual-filtration design is
typically used in a free-return
application.
The horizontal, GEH model, allows
the installer flexibility in design
applications such as a dual filtration
option. With the dual filtration
design, the unit will contain a lower
static which translates into a
decrease in filter maintenance. For
installation of a dual filtration
accessory for the GEH model, verify
that an extra set of return-air filter
racks and filter have been ordered
from the factory. This accessory will
be shipped separate from the unit,
and should be located in a separate
box than the unit.
1. Remove the return-air side panel
from the GEH unit. This panel is
held in place by six Torx® head
screws.
2. Install the top/bottom filter rack
at the new opening. The 1"/2"
(25.4/50.8 mm) adjustable filter
rack is held in place with four
Torx® head screws that once
held the panel.

filter.
Return-Air Duct Panel
Note: The ducted panel design is
typically used in combination
with a field installed ceiling
filter rack design.
The return-air arrangement may be
easily converted from a free return-
air system, to a ducted return-air
system with the addition of a return-
air side panel on the GEH unit. By
replacing the filter racks with the
return-air panel, a complete seal
from the ductwork to the unit is
possible. The 1 1/2" (38 mm) duct
flange facilitates ease of field hook-
up to the mechanical system.
1. Install the return-air duct panel to
the return-air opening with the
six Torx® head screws provided
for the filter rack assembly.
